Route of Synthesis (ROS)
| Conditions | Yield |
| With sodium hydroxide In 1,4-dioxane; water at 20℃; for 1h; pH=10 – 11; Experimental Procedure This synthesis is in accordance with Galbiati, B.; Ferrario, T.; Merli, V. WP 0110851(2001). A 250 mL three-necked flask was loaded consecutively with water (20 mL), 1,4-dioxane (20 mL) and L-lysine (2.1 g, 14.4 mmol). The mixture was stirred until complete dissolution. The pH was adjusted to about 10.5 by addition of 30% NaOH. Benzylchloroformate (5.2 g, 30.6 mmol) was added while maintaining the pH at about 1011 by adding at the same time 30% NaOH. At the end of the addition, the reaction was stirred at 20° C. for about 1 hour. The pH was adjusted to 5 with 37% HCl. Ethyl acetate (30 mL) was added and the pH was adjusted to 1 with 37% HCl. The mixture was stirred at room temperature for about 30 minutes, the organic layer was separated and the aqueous layer was extracted with ethyl acetate (20 mL). The combined organic layer was washed with brine (30 mL), and dried over Na2SO4. Then, the solvent was evaporated to yield a yellowish oil (6.0 g, 99%). The oil was pre-dried by azeotropic distillation with benzene. | 99% |
| With sodium carbonate In diethyl ether; water at 0℃; for 5h; Experimental Procedure 1.1 Step 1, 1. 155 mol of Cbz-Cl was dissolved in 100 mL of diethyl ether solution,200 mL of a 10% NaCO3 aqueous solution containing 0.0645 mol of L-lysine was added dropwise,After the addition was completed, the reaction was maintained at 0 ° C for 5 hours, and the product was obtained with an appropriate amount of 10% lemonAcidified and extracted with chloroform,The reaction layer was washed with water to give a large amount of waterN, N’-bis-benzyloxycarbonyl-L-lysine,The yield is about 95%. | 95% |
| With sodium carbonate In diethyl ether; water at 0℃; for 5h; Experimental Procedure 1.1 Step 1 Step 1, 0.322 mol of Cbz-Cl was dissolved in 100 mL of diethyl ether solution,200 mL of a 10% NaCO3 aqueous solution containing 0.055 mol of L-lysine was added dropwise,After the dropwise addition to maintain the temperature 0 reaction 5h,The resulting product was acidified with an appropriate amount of 10% citric acid and extracted with trichloromethane.The product was washed with water and evaporated to give a large amount of N, N’-bis-benzyloxycarbonyl-L-lysine,The yield is about 93%. | 93% |
